Hereinafter, the technical solutions of the embodiments of the present disclosure will be described with reference to the drawings in the embodiments of the present disclosure. The interference report control method, user equipment and network-side equipment of embodiments of the present disclosure may be applied to wireless communication systems. The wireless communication system may adopt a 5G system, or an Evolved Long Term Evolution (eLTE) communication system, or a subsequent evolution communication system.

FIG. 1 is a diagram illustrating the configuration of an interference reporting control system according to some embodiments of the present disclosure. As shown in FIG. 1, the interference reporting control system comprises a User Equipment (UE) 11 and a network-side equipment 12, where the User Equipment 11 can be a mobile phone, a Tablet Personal Computer, a laptop. It may be a mobile communication device such as a laptop computer, a personal digital assistant (PDA), a mobile internet device (MID), or a wearable device. In some embodiments of the disclosure, user equipment 11 is not limited to any particular type. Said network-side equipment 12 is a 5G network-side equipment (e.g. gNB, 5G NR NB), or a 4G network-side equipment (e.g. eNB), or a 3G network-side equipment (e.g. NB), or a subsequent evolution communication system. network-side equipment, etc., and in some embodiments of the present disclosure, the network-side equipment 12 is not limited to any particular type.

In 5G NR systems, besides Connected and idle states, an independent RRC state called inactive state is introduced. Here, the idle state and the inactive state are also called a non-connected state. Accordingly, some embodiments of the present disclosure may be applied to user equipment in idle or inactive states in eLTE systems or 5G NR systems.

Currently, the LTE Carrier Aggregation Enhancement (Enhancing CA Utilization, EuCA) project plans to introduce a fast activation/deactivation function to enhance the carrier aggregation technology. Here, the fast activation/deactivation function is carrier fast activation/deactivation applying to eLTE systems or carrier fast activation/deactivation applying to 5G NR systems or applying to 5G NR systems. Refers to Bandwidth Part (BWP) fast activation/deactivation and so on.

Here, in the carrier fast activation/deactivation technology, one possible method is that the UE performs measurements in the non-connected state, the UE determines that there are measurement results in the non-connected state, and the network-side equipment When the UE intends to receive the measurement results in the disconnected state, or the network-side equipment requests the UE to report the measurement results, the UE shall report the measurement results in the disconnected state to the network-side equipment. , or report that disconnected measurements are available. In this way, the network-side equipment can quickly configure and activate the UE's carrier based on the measurement results reported by the UE.

Due to different network and service needs, the same UE may be equipped with different radio transceivers such as LTE, 5G, WIFI, Bluetooth, GNSS. The UE's receiver may experience interference from the transmitter at adjacent or harmonic frequency portions. So there is an IDC problem in the UE. There may also be an IDC problem during measurements when the UE is disconnected, which may cause the LTE CA frequency point measurements to be incorrect. Therefore, if the UE detects an IDC problem during measurements in disconnected state, it needs to somehow record the IDC problem and report the IDC problem to the network side equipment. Since the UE has no RRC connection with the network side equipment in disconnected state, the signaling flow in the prior art cannot be used to solve the UE's IDC problem in disconnected state measurements.

In view of this, embodiments of the present disclosure propose a solution and associated signaling flow to the IDC problem present in measurements in disconnected state.

To achieve the above objectives, some embodiments of the present disclosure provide an interference reporting control system as shown in FIG. 1, and provide an interference reporting control method applied to said control system. the interference report control method;

controlling interference reporting behavior based on interference reporting conditions when the UE detects radio interference during measurements in a disconnected state. Here, the wireless interference includes in-device coexistence interference.

In some embodiments of the present disclosure, if the user equipment detects IDC interference during the measurement in the disconnected state, the measurement in the disconnected state is performed by controlling the interference reporting behavior based on the interference reporting condition. It can solve the IDC problem that exists in , and improve support for enhanced carrier fast activation/deactivation schemes. As a result, the network-side device can transmit setting information for canceling radio interference based on the interference information from the user device, so communication performance can be improved.

FIG. 2 is a flowchart diagram of an interference reporting control system provided by an embodiment of the present disclosure; As shown in Figure 2, the interference reporting control method applied to the UE comprises the following steps:

Step 101: Control the interference reporting behavior according to the interference reporting condition when radio interference is detected during measurement in the disconnected state. Here, the wireless interference includes in-device coexistence (IDC) interference.

In some embodiments of the present disclosure, the UE may initiate disconnected state measurements based on the measurement configuration information sent from the network-side equipment, or may Based on this, measurements in the disconnected state can be started.

measurement type, e.g., Reference Signal Receiving Power (RSRP), Reference Signal Receiving Quality (RSRQ), Signal to Interference plus Noise Ratio (SINR), or combination,
Measurement reporting thresholds, eg RSRP threshold, RSRQ threshold, SINR threshold, or any combination thereof.

In embodiments of the present disclosure, if the user equipment detects IDC interference during measurements in the disconnected state, by controlling the interference reporting behavior based on the interference reporting condition, It can solve the IDC problem and improve support for enhanced carrier fast activation/deactivation schemes. As a result, the network-side device can transmit setting information for canceling radio interference based on the interference information from the user device, so communication performance can be improved.

In some embodiments of the present disclosure, said disconnected state may be an idle state or an inactive state. In other words, the interference report control method according to the embodiments of the present disclosure is applicable to idle UEs, and is also applicable to inactive UEs. As a result, the interference reporting control methods according to some embodiments of the present disclosure are also applicable to eLTE systems and applicable to 5G NR.

In some embodiments of the present disclosure, interference information may or may not be reported based on interference reporting conditions. Also, when determining interference information reporting based on an interference reporting condition, the step of controlling interference reporting behavior based on the interference reporting condition includes:
During the process of the UE switching from the disconnected state to the connected state or in the connected state, reporting the interference information to the network-side equipment.

As can be easily understood, the timing at which the UE reports the interference report information to the network side may be during the process of the UE being switched from the non-connected state to the connected state, or when the UE enters the connected state. you can

Furthermore, during the process of the UE being switched from the disconnected state to the connected state or in the connected state, it reports the interference information to the network-side equipment. The step of reporting interference information to network-side equipment includes:

Reporting interference information to the network side equipment via a third message Msg 3 or a fifth message Msg 5 while the UE initiates RRC connection establishment or RRC connection recovery.

In the connected state, the UE reports the interference information to the network-side equipment via the connected state dedicated signaling.

Here, Msg3 can be at least one of the RRC connection establishment request message RRCSetupRequest and the RRC connection restoration request message RRCResumeRequest. Msg5 may be at least one of RRC connection establishment complete message RRCSetupComplete, RRC connection recovery complete message RRCResumeComplete.

Here, the connection state dedicated signaling can be at least one of a UE information response message UEInformationResponse and a UE assistance information message UEAssistanceInformation.

Interference indication information, affected measurement frequency region, affected measurement region, affected measurement type, affected measurement time region, affected Wireless Access Technology (RAT), affected system type.

Also, the interference indication information is used to indicate whether the UE has detected an IDC problem, for example, 1 bit indicates true/false.

Also, the affected measurement frequency region may include at least one of an affected frequency region, an affected bandwidth Bandwidth, and an affected bandwidth part (BWP). Specifically, the affected frequency points may be the frequency points measured based on the UE CA capability, or the measurement frequency points included in the measurement configuration information.

Also, the affected measurement region may be a measurement target region included in the measurement setting information, and the affected measurement type may be the measurement type included in the measurement setting information.

Also, the affected measurement time domain can be understood as the affected time information temporal information, eg subframe mode subframe pattern or slot mode slot pattern.

Also, the affected RATs are Evolved UMTS Terrestrial Radio Access (Evolution
It may be a radio technology such as UMTS Terrestrial Radio Access (EUTRA), New Radio (NR), Industrial Scientific Medical (ISM), Global Navigation Satellite System (GNSS).

Also affected system types are GPS (Global Positioning System), Global Navigation Satellite System (GLONS), Beidou System (BD), Galileo Positioning System (Galileo), Local Area Connection (Wireless LAN, WLAN), Bluetooth, etc.

In an embodiment of the present disclosure, the interference reporting conditions may be pre-promised by a protocol, obtained by interference report configuration information sent from the network-side equipment, or promised by the UE to the network-side equipment. You may These three different cases will be specifically described below.

If interference reporting conditions are pre-promised by the protocol, one of the following interference reporting conditions is promised by the protocol: When radio interference is detected during measurements in the disconnected state, the UE always informs the network side equipment. Report interference information, or determine whether the UE has the interference detection assistance capability, and if the UE has the interference detection assistance capability, report the interference report information to the network equipment. In this case, the UE can autonomously report the IDC problem.

Moreover, if the interference report condition is obtained by the interference report configuration information sent from the network-side device, the interference report configuration information includes at least one of the following:
information to indicate whether the UE reports interference;
Interference reporting threshold information when instructing the UE to report interference.

If the network-side device allows the UE to report IDC problems, the interference report configuration information includes information for instructing the UE to report interference. On the other hand, if the network-side equipment does not allow the UE to report IDC problems, the interference reporting configuration information includes information indicating that the UE does not report interference.

The interference report threshold information includes at least one of an interference report threshold and an interference report offset threshold. Here, the interference reporting offset threshold is an offset threshold relative to a certain reference value, which may be defined as the measurement reporting threshold in the measurement configuration information.

Further, if the UE initiates measurement in disconnected state based on the measurement configuration information sent from the network side equipment, said interference report configuration information may be sent by an RRC message carrying said measurement configuration information. . That is, the interference report configuration information and the measurement amount configuration information may be included in the same RRC message and transmitted. The interference report configuration information and measurement configuration information may be sent in different RRC messages.

Further, if the interference reporting condition is obtained by interference reporting configuration information transmitted from the network-side device and includes an interference reporting threshold and/or an interference reporting offset threshold, controlling interference reporting behavior based on the interference reporting condition. The step is
The measurement result in the non-connected state of the UE is less than or equal to the interference reporting threshold, and
If at least one of the deviation between the measurement result in the non-connected state of the UE and the measurement report threshold is greater than or equal to the interference report offset threshold,
and reporting interference information to network-side equipment.

In addition, considering that the UE can temporarily change the interference reporting capability, when the UE changes the interference reporting capability, the network equipment needs to reconfigure the interference reporting configuration information, so the interference reporting condition may be promised by the UE to the network side equipment.

In some embodiments of the present disclosure, if the UE detects an IDC problem during disconnected measurements, it may process at least one of measurement behavior, measurement results accordingly.

Specifically, if the UE detects an IDC problem during measurement in disconnected state, the measurement behavior may perform any of the following processes.
ceasing measurement behavior in the disconnected state;
suspending measurement behavior in a disconnected state;
Continuing the unconnected measurement behavior.

Here, how the UE specifically handles the measurement behavior is determined based on the impact of the IDC problem on the measurement result. The UE may stop or suspend the disconnected measurement behavior if the impact of the IDC problem on the measurement results is large enough to potentially invalidate the disconnected measurement behavior. If the impact of IDC problems on measurement results is acceptable, the UE may continue with disconnected measurement behavior.

Also, if the UE detects an IDC problem during disconnected state measurement and the disconnected state measurement result meets the preset conditions, the UE reports the measurement result to the network side device or makes it available to the network side device. Report that there are measurement results.

Here, the preset conditions include at least one of the following:
that the measurement result is equal to or greater than the measurement reporting threshold;
that the measurement result is equal to or greater than the interference reporting threshold;
A deviation between the measurement result and an interference reporting threshold is less than or equal to an interference reporting offset threshold.

In addition, if the measurement result does not meet any of the above conditions, the UE may report the measurement result to the network-side equipment. It is advantageous for the network-side device to transmit setting information for eliminating radio interference and improve communication performance if the network-side device performs auxiliary diagnosis of the IDC problem based on the measurement results.
